UILabel UITextField UITextView

Question

What is the fundamental difference between the two?

Is a UITextField not edited efficiently by UILabel ?

Are they essentially the same?

Answer 1

• UILabel : "The UILabel class implements a read-only text view."
• UITextField : "A UITextField is a control that displays editable text and sends an action message to the target when the user presses the back button."
• UITextView : "The UITextView class implements behavior for a scrollable multi-line text area."

So:

• read-only shortcuts
• Text fields are editable and provide a horizontal search for characters (without actually scrolling) when the text is too long to be displayed simultaneously. Commonly used to enter short text.
• Text views are also editable, but provide vertical scrolling when the text is too long to display all in one.

Answer 2

In addition to the answers above, a UITextView has selectable text. This means that you can copy it or make the device speak text.

Answer 3

• UILabel - used for static text rendering,
• UITextField - input field,
• UITextView is a multi-line input field

Also in addition to this: only with UILabel you can get the automatic shrink function, otherwise you must implement this (if necessary)
